" convnennmne MACHINE.

Application filed December 10, 1919. Serial No. 343,710.

The present invention is a machine for handling coin, and more particularly for melting change in transactions where the expeditious delivery of the exact amount of change is a desideratum.

The object of the present invention primarily is to provide a machine for making change the parts or" which are so related. as to attain an exceeding simple organization of the machine structure; a highly compact arrangement of the operative elements, and a resultant relative low cost of manufacture in the production of the parts, as well as their assembly in the completed machine. The machine, therefore, requires but small space for its accommodation, and the simplicity of its construction insures a minimum degree of liability to impairment or derangement of its parts.

The invention also has in contemplation the production of a coin handling machine in which the change-making instrumentalities are controlled bya plurality of keys placed in banked relation to afford the most convenient access by the operator, and so arranged in respect to each otherthat, the. formation of the various change combina tions within the range of the machine may be effected with rapidity and ease.

Furthermore, the invention also aims to provide a machine of the'characte'r mentioned in which but a minimum expenditure of power is required for the operation of the chance-making instrumentalities, and wherein the power is directly applied to the several coins to be displaced in making up the various change combinations. This demands but little effort by the operator in manipulating; the actuating devices and enables tree operation of the machine.

A further object to be attained isthe construction of the change-making devices in such manner that the power required for their operation is uniformly distributed' therethrouojh to the ultimate pointof application to the coin to be ejected.

Furthermore. the present invention also seeks to provide simple and efficient mechaui n tor locking the coin ejectors against movement under predetermined conditions prevailing in the coin receptacles. thereby preventing operation of the machine when the supply of coins of one or more of the '12 is designed to rest.

denominations necessary for completing any particular change combination has become depleted.

ther objects and advantages of the invention will'appear as its character more fully is developed in the subjoined description, the'invention consisting; substantially in the novel construction, combination and arrangement of parts herematter specified, illus-' Fig. 2 is a vertical sectional View of the machine across its narrow dimension.

Fig. 3 is a top plan view thereof, partly in section.

Figs. 4:, 5 and 6 are detailed sectional plan views, on an enlarged scale, through one of the coin receptacles,illustrating the coin ejector thereof and itslocking bolt in different positions.

Referring now in detail to the accompanying drawings, the numeral 10 designates the casing of the herein described machine. Thisis substantially rectangular in its, cross sectional plan contour, but it is obvious that its torm'in this respect may be varied. The rear wall of the casing 10 rises to a point elevated above the front wall thereof, as clearly illustrated in Fig. 2, where a top 11 is provided and against which a coin tray The casing 10 is equipped with a bottom plate 13, which latter is set into the lower end of said casins at a point above the lower edges of its walls, therebv providing a clearance space beneath said plate. At the'front of the casins 10 a horizontal guide plate 14 is located, which plate extends between the side walls of the casing, and in said plate 14 is posi' ti oned the series of operating keys, arranged in bank. formation, to be hereinafter described. It will thus be seen that the front of the casino, at the point where the operating keys are located, is in a much lower plane 12. and :as the coins :are discharged from the latter they fall into said chute and pass down the same to the delivery receptacle 16.

This arrangement also enables the delivery chute 15 to be placed substantially at the mid-portion of the casing 10 between the front and rear walls thereof, the same being positioned between the operating keys and the coin tray, and likewise after-ding space between the coin tray 12 and the rear wall of the casing 10 for accommodating certain of the operating elements to be hereinafter described. The walls of the delivery \chute 15 are parallel and pass straight through the machine from one side to the other. The chute, therefore, can be placed so that it will discharge either to the right or left side of the machine.

The casing constructed as above described affords a highly compact structure, and permits the mechanism of the machine to be arranged in small compass, thereby economizing in the size of the casing and requiring but comparatively little space for its accommodation when in use.

The coin tray includes a plurality of coin receptacles or chutes 17 formed by the back of the tray 12 and a plurality of side walls 1-8. The lower ends of the side walls 18 of each chute are of wider dimension than the upper ends thereof, and :are slightly curved towards each other, as at 19, to pre vent frontal displacement of the coins except in the manner hereinafter noted. The lower extremities of the bent portions 19 are cut :away to form discharge notches 20,

and said notches are immediately "contiguous to the bottom 21 of the tray 12., and thereby provide egress points at the lower ends of the chutes 1.7 for the coins when being displaced therefrom. The discharge notches 20 may vary in size in accordance with the thickness of a given denomination of coin or in accordance with the number of coins of a given denomination to .be displaced from the respective chutes when the ejecting mechanism is actuated. For instance, it may be desirable to discharge two or more pennies from the chute containing the same, or other denominations of the coins may be discharged in this manner at a single move ment of the ejecting mechanism, dependent upon the particular change combination eel.

which it is desired to make. In such event the varying sizes of the discharge notches 20 will provide for the proper displacement of the coins.

The bottom 21 of the tray 1-2 has a series of transverse grooves '22 one of which is :arranged beneath each of the coin chutes 17 and each of these grooves 22 receives a coin ejecting finger 28 which is pivotallyconnect .as at 2&, to the upwardly extending short These bell of a bell crank lever 25.

crank levers 25 are each provided with oppo- Y to each of said lugs .29 is a guide pin 30 that engages the ejecting finger .23 of the particular lever .25 with which the guide pin 30 is associated. A coil spring 31, of relatively weal: strength, surrounds each of the guide pins 30, and exerts its pressure against the ejecting finger 23 immediately above to press the ejecting finger upwardly, and maintain it in proper operative relation to the groove 21 ofthe particular coin chute 17 with which the-guide finger co-operates toinsure its contact with the lowermost coin of the stack in that chute.

All one side wall 18 .of each of the chutes V relatively narrow at their upper ends and.

comparatively broad at their lower ends.

The purpose of narrowing the upper ends ofthe springs is to provide a full clearance between the upper portions of the side walls of each chute so that the .coins in bulk can be inserted easily .andnot contact with the springs .duringsuch insertion. In doing this the coins .are held between the thumb and a finger somewhat above the bottom of the coin tray andare filled into the machine with a downward motion. The wedgeoshape of the springs ins u'es the easy entrance of the coins in bulk into the respective chutes 17 with a gradual Wedg ing action, the coins clearing the rigid portions of the springs at tieir narrow upper ends and contacting only with the lower broadened ends which gradually and gently are forced. back as the coins onter their respective chutes. The width of the lower portions of (the springs is such as to contact with the adjacent edges of the coins, whereby extent of movement of the lower ends of the springs away from the side walls 18 is limited by the coins. dition is utilized as will presently appear.

This con- It has been stated that the present invention seelrs to provide simple and etficient mechanism for locking the coin ejectors against movement under predetermined conditions prevailing in the coin receptacles and thereby preventing operation of the machine when the supply of coins of one or more denominations has become depleted. Preferably this locking of the coin ejectors is effected when a predetermined number of coins remains in the chute, thus making it possible for a limited number of payments still to be made upon freeing the machine of its locked condition as hereinafter described. It is obvious, however, that the supply of coin may be wholly depleted before the locking action ensues, in which event no further payments can be made until the chute fromivhich the coins have been completely discharged has been refilled with the coins of the denominations which it contains. Inasmuch as the locking of the machine with a predetermined number of coins still remaining in the chutes gives notice to the operator of the necessity of replenishing the supply of coin, but still permits limited payments to the extent of the number of coins remaining, the machine is illustrated as adapted to meet these latter cond tions. To this end the lower forward edge of each of the springs 32 is cut away to form a clearing notch 33. The dimensions of. this notch are such as to receive the combined thickness of the predetermined number of coins which it is intended shall remain 'in the chute after the coin ejectors have become initially locked. This number may be one, two, three or more as desired. 'So long as the stack of coins in the chute exceed in' number the coins which the notch 33 will receive, the movement of the lower end. of each spring 32 away from the side wall 18 is limited by contact with the excess coins. lVhen, however, the stack becomes reduced to the predetermined number under which the locking action arises, the notch 33 permits the lower end of the spring 32 to clear the remaining coins and the machine becomes locked. By the formation of the notch 33 a finger 34L is provided at the lower extremity of each spring, and each of said fingers 34 carries at its rear edge an engaging tooth 35 the free end of which is received by a notch 36 (Fig. 4) extending crosswise of a locking bolt 37, one of which isprovided for each of the coin chutes 17 These locking bolts 37 are slidably mounted in a groove 33 formed at the rear edge of the bottom 21 of the coin tray 12, said groove 38 intersecting the grooves 22. The

inner end of each of said bolts 37 is beveled,

as at 39, so as to present'an inclined contact face to the inneren d 0f the adjacent ejectingfinger 23. Each locking bolt 37 is designed to be projected across the mouth of the adjacent groove 22 which guides the ejecting finger 23 to the lower end of the particular coin chute with which the bolt is associated In this manner, when the bolt is projected entirely across said groove, the forward movement of the ejecting finger 23 is barred, and this, therefore, locks the machine against discharge of coins from the chute until the locking bolt 37 thereof has been retracted. The projection of the locking bolts 37 across the grooves 22 is effected by the several springs 32, but not until the stack of the coins in the respective chutes has been reduced in number to such an extent, as above indicated, that the notches 33 will permit the springs to clear those coins remaining in the chutes beneath said notches' When this condition arises the lower ends of the springs 32 move inwardly, and at such movement the teeth propel their respective locking bolts 37 across the grooves 22 The relation of the parts just described under the conditions recited is illustrated in Fig. 6. This is the locked condition of the machine, In Fig. 5 the rela tion of the parts is illustrated as when the machine is in operating condition for the making of payments, At this time the supply of coin in each of the chutes is such that the edges of the coins above the notch of the spring 32 are in contact with the broadened lower portions of said spring. This contact of the coins forces the spring 32 of'each chute towards the side wall on which it is supported and holds the spring in that position, and the beveled end 39 of the bolt 37 extends into the path of forward movement of the ejecting finger 23. In this movement of said finger its forward end slides over the-beveled end of the bolt 37, thereby forcing the bolt backwardly in the groove 38, and moving the lower end of the spring 32 away from contact with the edges of the coins and towards the side wall 18. The coins of the. stack, therefore, may drop freely by gravity to the lower end of the chute. Fig. 4 illustrates the relation of the ejecting finger and the locking bolt, together with the'retracted position of the lower end of the spring 22 and its clearance relation to the edges of the coin, as just described. After discharge of the lowermost coin the ejecting finger 23 moves rearwardlv, and after it passes the beveled'end of the bolt 37 the spring 32 asserts itself to restore the lockingbolt to the position illustrated in Fig. 5. at which time further movement of the bolt across the groove 22 is prevented by the lower broadened. end of the spring 32 again contacting with the edges'of the coins above the notch 33.

the clearance afforded by that notch permits the lower end of the spring to move to the added extent of projecting the bolt 37 entirely across the groove 22., and thereby establishing locked condition of the machine. The fact, how-ever, that a predetermined number of coins still remains in the chute enables further payments to be made limited to the extent of the number of these coins. This is desirable where it is not possible for the operator immediately to insert a stack of the coin in the chute when the machine has become locked. To permit the machine to be cleared of this locked condition a releasing slide 40 is mounted in suitable bearings 41 carried by the tray 12, said slide on tending across the entire width of the tray and having a plurality of contact pins 42 which project through slots 43 in the tray. Gne of said contacting pins 42 extends into each of said chutes 17 and into position for engagement with the spring 32 thereof. By pushing the slide 40 so that the pins 42 contact with the springs 32, the latter move towards the side walls of the chute on which they are mounted, and the bolts 37 move.

away from the grooves 22 to clear these grooves for forward movement of the ejecting fingers The slide 40 may be held in this releasing position, a notch 44 being formed therein for receiving a locking pawl 45, and while so held it is obvious that the coins remaining in the chutes may be discharged therefrom.

If it be desired that the locked condition of the machine shall not arise until all the coins have been discharged from the several chutes 17, the notches 33 will be dispensed with, the lower ends of the springs 32 remaining of uniform width, and affording no provision for clearance of any of the coins until the entire stack has been discharged.

The horizontal arms of the bell crank levers 25 project towards the front of the machine, and to a point beyond the discharge chute 15. At their forward ends they are engaged by a plurality of actuating plates 46. These plates are formed of thin attenuated metal, and each is provided with a vertical key stem 47 terminating at its upper end in a contact button 48. The plates 46 are disposed between the guide plate 14, through which said key stems 47 proiect, and the upper sides of the horizontal arms of said levers 25,thereby economizing in the space at the forward end of the machine, and at the same time enabling operation of the coin ejecting instrumentalities by a limited movement of the actuating plates. Each of said plates 46 has a downwardly extending guide stem 49 which passes through a suitably formed perforation in the bottom plate 13, and at an appropriate point the stem 49 has formed thereon a pair of shoulders 50 against which the upper end of a coil spring 51.bears.' The lower end of this spring contacts with the bottom plate 13, and said spring, 51 serves to return its actuating plate 46 to its normal or uppermost position when pressure is released from the key stem thereof It is to be observed that the key stem 47 and the, guide stem 49 of each of the plates 46 are arranged in substantial alignment, so that the pressure applied to the key. stem extends directly to the guide stem 49, thereby insuring positive action of the plates 46 when the same are depressed, and giving the most direct application of thepower to the plates with a minimum of friction. ranged-above and the guide stem arranged below each actuating plate 46 a long sliding leverage is obtained which makes possible easy and more uniform operation of the machine, and this is especially true when the longer plates are employed. Furthermore, the location of the guide stems 49 at the under edges of. the plates 46 affords a con- V itl'i the key stem arvenient position for the return springs 51 in the economical and compact arrangement of the operativeparts within the casing. v

Each of the plates 46 also extends over the requisite levers 25 for operation thereof in the making of the particular change combination for which that particular plate is intended. That only those levers 25 to be included in such operation may be actuated, each of the plates 46 has a notch or notches 52 formed in its-lower edge and immediately above the individual lever 25, or levers, not to be actuated. on the depression of that plate. As illustratedin Fig. 1, the particular plate 46 shown in elevation therein actuates those levers 25 which will produce ninety cents in change, there being but one notch 52 in this plate, and as the latter is depressed the same contactswith those levers 25 which will cause operation of the ejectingfingers 23 in the fifty-cent, twenty-five-cent, tencentand five-cent chutes.

, As illustrated in Fig. 3, the two banks of twelve keys each, thekeys of each bank being disposed in staggered croftset relation with respect to the keys of the other bank. The keys of the first bank are arranged preferably so that the first key at the left hand side of the machinewill produce one dollar in change; the next five keys-are designed to deliver change in the combinations of ten, twenty, thirty, forty: and fifty cents; the next two keys will actuate the delivery instrumentalities for ejecting pennies singly and twoat a time, re spectively, while the remaining four keys of the firstbank are designed for actuating those plates which will produce sixty, seventy. eighty and ninety-cent combinations. In the rear bank of the keys, com- 'mencing at the left hand end thereof, the

first six keys are designed to actuate those keys include V forty-five and fiftyefive cents; the next two plates which will deliver change in combinations of five, fifteen, twenty five, thirty-five,

are for delivery of three and four-cent combinations, respectively, while the remaining four of the rear bank will actuate those plates by which delivery of the sixty-five, seventy-five, eighty-five and ninety-five cent combinations are effected. This arrangement positions the key for the one dollar combination at the most convenient point, and I where it is freely accessible, while those keys for delivering single pennies, and in combinations of two, three and four, are arranged at substantially the centers of the two banks.

By reference to Figs. 1 and 2 it will be noted that the front bank of the keys does not extend as high as the rear bank. This makes it possible to operate any key of the rear bank without curving the finger and without the necessity of avoiding contact with the front bank. The degree ofdepression of the keys of the rear bank carries the same, when operated, only as low as the plane occupied by the keys of the front bank in their normal position, or when they are at rest. "The keys, therefore, of the rear bank can be operated with facility and ease regardless of the presence of the front bank.

The spring 51 of each actuating plate 46,

acting directly upon the latter, will restore the plate to itsnormal position when pressure on the key stem is removed, but this does not restore the bell crank levers 25 to their normal positions. To effect this a retracting spring 53 connects each of said levers with the ledge 28, so that when the plates 46. are raised by their respective springs 51, the levers 25 which have been depressed thereby are also restored to their normal positions by the springs 53 connectedv thereto.

In the operation of the hereindescribed machine, the several chutes 17 being supplied with the required coins of the several denominations designed to be placed therein, depression. of the particular actuating plate 46 by the key stem 47 thereof actuates the levers 25 in the particular change combination controlled by that par-. ticular plate, thereby projecting the ejecting fingers 23 forwardly in the grooves 22 of the several chutes of the coins included in that combination. The lowermost coin of each of these several stacks is thereby ejected into the delivery chute 15 where the same gravitates to the delivery receptacle 16. Pressure being released from the key stem 47 of the plate, the spring 51 thereof raises the plate to its normal-position, and

the springs 53 of the levers 25 thereby actuated likewise restore these levers to. their normal position-and retract the ejecting fingers 23 from beneath the stacks of the coins. So long as a sufiicient number of coins wardly in the groove, as illustrated in Fig.v 4, the lower end of the spring 32 is released from its contact with the coins so that the coins may freely gravitate to the lower end of the chute 17 to take the place of the lowermost coin-ejected by said finger- When the stack of coins has been reduced to the point that only the predetermined number whose combined thickness will be received by the notch'33 remains, clearanceis afforded for the movement of the lower end of spring 32 and the same moves thelocking bolt 3Tentirely across the groove 22, thus precluding advancing movement of the ejecting finger;

23. The machine thereby becomes locked, and until the. chute has; been replenished with a new supply of coin, or until the releasing slide 40 has been operated to clearthe machine of its locked condition, the ejecting finger of the particular-chute which has become depleted of its coin is no longer operative.

The machine described provides a compact organization of the parts and theapplication of the power from the key stems 47 to the coin inthe chutes is direct and dis-v tributed in such manneras to afford posi; tive and; easy operation of the several ele- As the ejecting finger forces the bolt backments included in the change-making instru mentalities.
